 ## VSCode Tasks

-- **View Go module documentation** task: installs `pkgsite`, if not done already
-  so, then starts `pkgsite` and opens VSCode's integrated ("simple") browser to
-  show the go-plugger/v2 documentation.
-
 - **Build workspace** task: builds all, including the shared library test
   plugin.
